The global burden of neglected tropical diseases

The neglected tropical diseases (NTDs) consist of a group of chronic, debilitating, and poverty-promoting parasitic, bacterial, and viral and fungal infections that are widespread among people in poor rural or peri-urban communities living in tropical or subtropical areas. However, due to population mobility, diseases such as Chagas disease can be diagnosed anywhere on the globe. The NTDs are disabling, disfiguring and deadly diseases impacting more than one billion people worldwide. They also impair physical and cognitive development, cause adverse pregnancy outcomes, and limit adult productivity in the workforce. The global burden of disease associated with the NTDs is comparable to other infectious diseases such as that of malaria or tuberculosis. Controlling or eliminating NTDs represents an affordable opportunity to improve the health of poor communities, which may ultimately promote social development.
